iNlPROVEM ENT IN PLASTERING TROWELS.

Specification forming part ofrLetiers Patent No. 36,757, dated October Q1, 1.6(2.

To @ZZ whom t may "concern:

Be it known that I, JOSEPH FLINT, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in PlasteringTrowels; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a perspective View, and Fig. 2 an elevation of the front end.

Similar letters designate corresponding parts in both of the figures. Y

As represented in the drawings, A is the plate, and B the handle.

My improvement is applied to that portion by which the plate and handle are connected, on which in a great measure the strength of the implement and facility of working it depend. A slender piece of metal, C, diminishing toward either end, is riveted to the back oitlielaa, longitud'iflTy'tli'mdfft'S-'Itli being ut ittle less than that ot the plate. This acts as a stiffener, giving strength.to the plate to prevent it from springing under the pressure t0 which it is subjected, and enabling a lighter plate to be used. From the largest portion of this piece, being a little forward of the center of the implement, the Astandard D arises, for supporting and giving suitable ele- ,vation'to the handle. At the top of this is the shank e, passing through" the wooden handle B, at right angles to the standard D, and parallel with the plate A. Transversely of the implement the standard is expanded into the form of a disk, midway between the shankw and plate, as shown in Fig. 2. l The'reverse side, or that underneath the handle,is convex, being rounded easily off to the edges f f, at which it is quite thin, giving by this form the requisite strength combined with lightness,

the metal being so disposed as to balance the implement from the center, rendering the operations and manipulating therewith far more facile and easy. This form is also especially designed to act as a finger-guard to protect the hand from wear when in use, and from contact with obstructions or falling matter.

In the ordinary standard for affixing the handle of this kind of implement, it is necessary to guard the hand by winding cloth or other similar material around the forenger to prevent its receiving injury from the chafing of the standard, and from other exposures to which it is subject. My invention overcomes that necessity entirely, as it presents a surface of a form that cannot be painful or injurious to the nger, while its extent adapts it for receiving the pressure against it, which is unavoidable in its use, without discomfort Vithout involving an increased amount of metal, and by simply disposing its greatest.` bulk and weight at what may be termed the balancing point of the implement, it renders its working so much easier that it seems far lighter in the hand of the operator than one of ordinary form and of the same weight.

Lightness is ot' paramount importance Where strength is not sacrificed, as it admits of quicker and freer handling, and consequently greatg er ease to the operator.

What I claim as my imvention, and desire to secure by Letters Patent, is

Forming the standard for attaching the handles of trowels with the transverse expansion D, substantially as and for the purposes here- Yin set forth.
